To all whom t may concern .f

lBe it known that, I, GEORGE IV. KAUSER, a citizen of the United States, and la resident of Chicago, inthe county of Cook and fState of Illinois, have invented certain new and useful Improvements in Cameras; and

l I do hereby declare thatthe following isa full, clear, and exact description thereof,

plate changing device removed My improved plate changing device is capable of use with any magazine camera, as for example,'y\vith the series picture, reflex camera, described 'in kthe application yabove `referred to. f In the yaccompanying drawings it is shown embodied in a unitary magazine structurey adapted to be. applied to the ordinary box camera.l l v 15 indicates the camera box,"which in this case is without the usual-plate holder, being open atthe rear end yas at 16. 17 indicates amagazine casing which is attached to said open end of the' camera boxin any` convenient manner. As shown, the rnagazine casing is ofthe same heightl as the camera box, but extends beyond the sides of saidbox.V f i Said casing has top and bottom walls 18, 18, front and rear walls 19, 20, respectively and an upright side wall 21,-t-he other upright side of the casing being open but being adapted `to beclosed by an yend member of the plate-changer as'will presentlyvappear. 1,

Inthe front wall 19, is an exposure 22, which opens'into they camera .box when the casing is attached `to it, afs/shown" in Figure 2.' The rear wall y20. has an opening vwhichy isl normally closed by .a light-proof .door 23, hinged along its bottom edge to the casing, toopen downwardly. v

eac/heide of the exposure opening 22, are seycured Vupright channel bars 24 which embrace the rear edges ofthe side wallsof the camera box. To the top and bottom walls 18 of the casing, are secured plates 25,- which overlap the top and bottom walls of the camera box, and which yare attachedthereto by screws or the like,'as shown in Figure 1.

Thus the casing is securedto vthe camera in asY to prevent the entrance'of y such manner light.

The magazine proper Consists 0f miope. i

O'y ther front wall 19, of the casing, at.

frame having top and bottom walls E2G, 277, respectively. and left and right hand side walls Q8 and 29 respectively, all of which are spaced inwardlyv from the correspoin` walls of the casing. The le'lt hand wi attached to the adjacent wall oit the cai. casingr and holds the niagaine l'ramc position with the rcar'ot the trame paced from the rear door 23 and with the trout ends of :its top and bottom valls 26,.. QT, abutting against the liront wall 19 of the casincr 1T.

The magazine trame is designed to hold a plurality ot loaded plate holders or septuins, as tor'example, twelve. f5() indicates the septunis (see Fig, l). lach septum is a rectangular piece t sheet nietal` the top and bottom margins ou. which are bent torwardlj' and downwardly to provide oppositely facing flanges 3l, said flanges delinw ing grooves to receive the top and hottom edges ot a sensitized glass plate 552. The septum is tace-d with a sheet oit paper. to prevent scratchingr ot' the seu" l'ized plate as it is inserted. into the groov i lett hand margin ot the septum. and has a marginal extension 'lfl at one side tor the purpose ot handlingr it. (Feer lli At the opposite side. it has a. loi tending' lange 35. which acts the sensitized plate when it is the septum. The flange El?) is curved vtoi'- vmrdljv between its top and lxotiom as indicated at :35X (see Figures 3 and 5.) The septums are provided on their hacks with numerical characters (sce Fi il) to iudicate their order ot succession in the magazine.

At the haelt oic the casinfl` li. the space between the rea r door and the rear end of the magazine trame. is located a siidahle plate-changer (See Figures and 1Q.) This consists a rectangular plate or hody 3T having forwardly extending top and hottom flanges 3S. which have slidingr hearing on the rear mai'` lnal partsot the top and hottoin magazv ie trame n'iemoers 26m-QT. iis shown in Figures 8 and l2, the top and hottom edges et' the plate changer arev preterahly rein'torced and stiilened h v hars To the right hand end of said plateschanger is secured an end member 4.0, which, when the platechanger in its normal position, closes the opening in the maffazine casing Awhich vcfives access to the plate compartment.

it collapsible bag all. is secured to said end meml er Ll0 and to the partv of the easing 1.7`

ahout the opening which it closes. in order to seal the plate-changer against the entrance of light during the operation of the plate-changer. A finger-hold plate 4i?. attached to the outer face oi the end memhcr 0 'servesY` a grip tooperate the plate changer.

At the inner end of' the plate-changer is Vvertical an extension lf3 which carries a spring controlled abutment il adapted to rock upon a axis. Said abutment, when the platechanger is in its normal position, stands in line with and adjacent to the tlange ot the rearmost septum in the mag azine and when the platerhanger is withdrawn from the casing 1T, said abutment will engage said flange and Yloi-ce the septum out with the plate-changer.

l5 indicates an upright rock shalt which is ournalled in the brace hars 39 olf the plate changer .near its inner end. The topend of said shaft is lient forwardly to provide a rock arm i6. Verticallyspaced, horizontal arms 47, are fixed to the shaft and extend toward the outer end of the plateclianger. The `free ends oit said arms are pivotally connected to the inner end of a shifter plate 48, which normally` stands back ot the rear most septum in the magazine. At the outer end ot' said plate is a hooked flange 49, which, when the plate changer is in its normal position in the casing` li', will engage the outer edge of the rearmost septum. A coiled. contractile springr connects the sha tt l5 with a point on the shifter plate 48 located a somewhat greater distance from said shaft l5 than the axes of the pivotal connections of the arms 47 with said plate. This spring acts to assist in moving the shifter plate trom its parallel position with respectto the plate-changer 36, to the position shown in Figure. 5. The outer end of lheshifter plate is normally engaged heneath a hook 5l on the plate changer.

Upon withdrawal of the platc-changer` just as it approaches the outermost limit of its movement. the arm 46 ol" the roch shaft 45 will engage a fixed pin 52 (see Figure l1) dependingT troni the top wall of the casing 17. whereupon, a further withdrawal will roch the shaft l?) to swingr the arms 4T lorwardly and with them, the inner end of the sli: plate into the position shown in iiigzure thespring 5l) assisting asrhetore pointed out.

There is mounted on the vertical wal129 ot the magazine frame adjacent to the Wall 1,9 ot the casing 1T, a vertically extendingr spring controlled guide roller Said roller is spaced from the said'wall a distance sntlicient for the end of the septum to be engaged between it and the wall 19, when said septum end (the septum having: been swung into the position shown in Figure 5 as laststatcd) is moved inwardly in the initial movement of the plate shifter 36, upon its return movement to its normal. closed position.

Said roller53 is mounted in an)7 suitable manner. so as to Yield somewhat away from the wall 19.1 and inwardly toward the center et the casing. to permit the septum to'be mowed and `guided between it and said adja c the plate changer,-

.at 19x, Figures e and a)l will cent wall 19, towards and finally into aposition parallel to said wa1l,`said roller holding the septum 'against said wall 19 during this movement. f As shown, said roller is mounted in a swinging frame 54, which is fixed to an upright shaft 55, journaled1 in` ears 56, extendin' horizontally from theV vertical' wall 29. `verticallydisposed kflat springf57, fixed" at the 'bottom to the side wall 29 of the magazine frame, has'its top end engagedagain'st a horizontal arm 58 at' the top of the ing for theyielding movement of the rollery frame54. Y

When the Vplate changer hasbeen moved inwardly a certain distance, the septum, by reason of its engagement between the roller 53 and the'wall 19 (which is also curved forwardly toward the opening 22 as indicated be swung mto and held in a plane parallel with and adjac'entto said wall 19.l Upon'urther inward` vmovement of the plate changer, the outer end of said septum wili'ber engaged by in'- wardly extending top and bottom pusher bars 59, provided onthe'end member 40 ofwhich' pusher bars will complete the inward lmovement ofr the tum-the parts f other exposure.

septum. f

As the plate changer is moved the arm 46 of the shaft 45 will strike the outer end of a flanged plate 60 (see Figures Band 11) fixedV tothe rear margin of' the topl wall 26 of the magazine frame. This will produce a rocking movement of the shaft 45 so as to swing 'the shifter plate 48 back into its original position, parallel with the body 37 of the plate changer.'- Openings 61 (see Figure 6) are Vprovided in the vertical magazine wall 29, in line with the pusher bars 59, which are located aboveA and below the roller 53, so as to permit ysaid pusher barsto move the septum into the desired position with line of the camera. When the `outer end ofthe septum passes the roller 53, said roller will be returned by the spring 57, to its normal position; the spring controlled abutment 44, on the plate changer, will yield to pass behind the rearmost septuml in the stack, and when the rplate changer has come to its normal position, will snap into engagement with the inner end y35 of said sep- Ltum;

and thev hook 49 onk the plate shifter 48, will engage the front end of said sepbeing thus allintheir normal, original position and ready to make an- The cycle of operations described is, of course, repeatedafter each exposure.

To hold the rearmost plates in their upright position when the plate changer is 1n its 'outward position, I provide a yielding swinging arm 62 (see Figures 9 and 11) which is pivoted at (53v Sto the magazine haft 55,-said spring providinwardly, 2

its center in the focalr frame. This arm is adapted to be engaged by the inner end of the plate changeras it moves inwardly to move it outof the way and will lautomatically swing into its up-` right position upon outwardmovementof the rplate changer.

"In order to keep the septums in the stack in line 'as they are shifted rearwardly in the magazine frame, I preferably provide spring lingers 64, 64, `at the" top and. bottom and adjacent tothe wall 29 of; the magaziner frame, f which ryieldinglyl engage the outer. edges vof theV septumsBO, and. hold them'again'st lateral shifting movement'.

`To keep track of the number of plates exposed, eachseptum carries a numbersuch cha-nger,*as said changer is moved inwardratchet wheel against' backward movement'.` Said 'ratchet has numbers, one Vfor each plate,'which numbers are'visible'through a second but smaller' openingv 70 in the door When all the 'plateshave f been exposed, the platechange'r is'moved outwardly, after which the door 23fis opened and the septums removed therethrough. '."The exposed plates are removed from the septumsand new ones 'substitutedl therefor, "after which all the kseptums .are ,agam replaced the rmagazine as before. Y v
